CRS Bridge domain traffic fail

[diego.macedo]

Hi,

We need bride traffic between bundle-ether and gigabitethernet subinterfaces that are connected to the same dridge domain, but the traffic isn't passing between them. Here is the relevan config:

interface GigabitEthernet0/2/2/9.15 l2transport
 dot1q vlan 15
!

interface Bundle-Ether1000.15 l2transport
 dot1q vlan 15
!
l2vpn

...

 bridge group NNItest
  bridge-domain NNItest15
   mtu 8986
   interface Bundle-Ether1000.15
   !
   interface GigabitEthernet0/2/2/9.15
   !

Can somebody help?

Is there a particular reason the bridge domain MTU is 8986 while the interfaces are 9000? First thing I would do is set them to the same MTU, including the physical interfaces. You should also be able to get some output from the "show l2vpn bridge-domain" command to assist with troubleshooting.

Hi Jason,

Bridge MTU is just for PW signaling purpose. Not dealing with data
forwarding. But both end of PW, bridge MTU must match, this is
mandatory.

Please make sure your link MTU on LDP enabled interface in your core
facing is enough to forward the packet.
